If you're dating a doctor and surrounded by doctors, lying about a major illness is not the best idea, as Dr. Lola Spratt discovers on 'Childrens Hospital' (Sun., 10:30PM ET on CN).

"I don't have a brain tumor," confesses Lola to Owen. "I just -- I couldn't think of a reason to break up with you." Owen replies, "That's just your brain tumor talking."

The Chief announces matter-of-factly: "Dr. Lola Spratt has a brain tumor." An exasperated Lola turns to Owen: "What?! You told everyone I have a brain tumor?" He says soberly, "You need your friends right now."

But even someone who actually is a friend interprets the news in an unexpected way.
